X = 2 means for whatever y value you select the x value will be 2. So if you graph a couple of coordinates it becomes quickly evident that x = 2 is a vertical line that crosses the x axis at 2.

Answer:
R - chart
Step-by-step explanation:
Range chart (R chart) is a control chart used for processes with two or more subgroups to determine if a process is stable or not. It monitors the mean and range of a normally distributed variable simultaneously collected at regular intervals during a given time. It is used when measuring small subgroups between two and ten at regular intervals from a process. Iy is a;so used for constant subgroups.
Answer:
z=0
Step-by-step explanation:
With lines of the form y=mx+b lines are parallel as long as m is the same->m=5
so we know the new line also has the form y=5x+b, so now we have to calculate the b to pass through (4,7)
for this insert x=4, and y=7 to solve for b
7=5*4+b
7=20+b
-13=b
so the parallel line through (4,7) has the equation y=5x-13
